Air freshener canisters

ABSTRACT

An air freshener canister includes a container, a nipple thereon and a cap threadably matable therewith. The cap can be positioned along the length of the nipple from a closed position with the cap rim against the exterior surface of the container and an open position wherein there is spacing between the rim and exterior surface. A volatile liquid in the container emits air freshener vapors. A wick runs from the liquid to the nipple. When the cap is in the open position, vapors escape from the wick through the spacing. When the cap is in the closed position the vapors are prevented from escaping. When the cap is removed from the nipple the container may be refilled with the volatile liquid. The escape of vapors may be increased or decreased by positioning the cap on the nipple to increase or decrease the spacing.

RELATED APPLICATIONS

This application is a Non-Provisional Patent Application claimingpriority of Provisional Patent Application 61/835,834 filed on Jun. 17,2013 and a Continuation-in-Part application of U.S. Ser. No. 29/458,128filed on Jun. 17, 2013 (pending), the entire disclosure of each of theseapplication is incorporated herein by reference.

FIELD OF THE INVENTION

This invention relates to air freshener canisters, and in particulardecorative, refillable canisters having a controlled release of airfreshener vapors into the environment that are suitable for use inenclosed spaces, such as motor vehicles, bathrooms and other rooms ofresidential or commercial establishments.

BACKGROUND OF THE INVENTION

Various different types of air fresheners or air freshener devices existfor dispensing a variety of different compositions into the environment.Most of these devices rely on evaporation from a solid or liquid airfreshener composition to produce a vapor that goes into the air.

Some of the currently available evaporation type air fresheners have acompartment that contains an air freshener composition that when exposedto the atmosphere the composition evaporates. Typically, the compositionfrom the compartment is at a rate that is dependent on the rate ofmovement of the air over the compartment. Such devices are notadjustable, in that the rate at which the composition evaporates isdependent solely on the environmental conditions, e.g., primarily airflow and to some degree temperature.

In some devices, an air freshener composition that vaporizes isincorporated into a solid carrier from which the substance evaporatesand enters the atmosphere, frequently, after a protective wrapping orcover is opened or removed. Typical of such devices is the ubiquitous,unattractive hanging card air freshener that hangs, for example, fromthe rear-view mirror or air conditioning vent of an automobile. Theeffectiveness of these devices is not adjustable, highly dependent onthe environmental conditions in the automobile and gradually diminishesin effectiveness over time.

Pumps and aerosol sprays exist that emit air freshener or air freshenercompositions. However, these may be dangerous to keep in a hotautomobile interior, as the pressurized container may become overpressurized, and possibly leak or explode, or otherwise become damaged.In addition, these liquids or gasses can damage the interior surfaces ofan automobile and may be explosive under certain conditions.

In spite of these numerous devices, there is still a need for an airfreshener device that enables the selective, controlled release ofvapors into the atmosphere, is refillable, is attractive and can bepositioned at various locations in, for example, an automobile.

There is also a need for an air freshener device that is attractive foruse in, for example, offices, automobiles, etc. that can be brandedwith, for example luxury brand logos and designs, whether original orunder license from the brand owner.

First Embodiment Medallion Air freshener Canister

A first embodiment for this invention, the Medallion Air FreshenerCanister, is shown in FIGS. 1 through 6.

Referring for example to FIG. 1, this embodiment the air freshenercanister 100 includes a means for suspending the air freshener from anobject. In the embodiment shown a cord 108 suspends the canister 100from the rear view mirror M of an automobile. FIG. 4 is a perspectiveview of the front of the air freshener canister 100 of this inventionusing a different type cord 108 for suspending from an object, e.g.,automobile rear view mirror M. Optionally, the air freshener canistermay be placed or mounted on a flat surface.

Referring, for example, to FIGS. 5, 6A and 6B, the air freshenercanister 100 is provided with a container 102 into which a volatileliquid composition L may be placed. The volatile liquid composition L iscapable of emitting air freshener vapor V at ambient conditions. Thecontainer 102 has an exterior surface 103 and a mouth opening 105through the exterior surface 103. The container 102 in this embodiment,as well as all the other embodiments described herein, may be made ofglass, plastic materials of adequate durability and tolerance, such aspolypropylene or polyethylene terephthalate, or any other materialsuitable for containing the volatile liquid composition L andfunctioning with the other elements of this invention.

Referring to FIGS. 6A and 6B, a nipple 122 is on the exterior surface103 of the container 102 and extends from the mouth opening 105. Thenipple 122 can be attached, e.g., glued, welded, screwed on to thesurface 103 to surround the mouth opening 105 or molded with thecontainer 102 to form a one piece molded structure.

The nipple 122 has an interior surface 128 and an exterior surface 130.A cap or knob 104 is provided that has a closed end 132, an open end134, a rim 136 around the open end 134 and an interior surface 138. Inits simplest form the cap 104 is an on-off control. In a moresophisticated version as depicted herein it can moderate the strength ofthe air freshener vapors V emanating from the canister 100.

The interior surface 138 of the cap 104 is slidably engagable with theexterior surface 130 of the nipple 126. Preferably, as shown in FIGS. 6Aand 6B, the exterior surface 130 of the nipple 126 has a first set ofthreads 140. A second set of threads 142 are provided on the interiorsurface 138 of the cap 104. These threads 140, 142 are slidablyengagable with each other to enable the cap 104 to be selectivelypositioned along the nipple 122 by, in the embodiment shown, turning thecap (or knob) 104 clockwise or counter-clockwise, e.g., see FIGS. 1 an2, arrows. Optionally, the cap 104 can frictionally engage the nipple122 or another configuration of threads can be used.

Referring to 6B, the cap 104 may be selectively positioned between aclosed position wherein the rim 136 is juxtaposed against the exteriorsurface 103 of the container 102. This may be accomplished by turningknob (cap) 104 clockwise to tighten the cap 104 on the nipple 126.

Referring to 6A, alternatively, the cap 104 may be turnedcounter-clockwise to an open position wherein there is a spacing 144between the rim 136 of the cap 104 and the exterior surface 103 of thecontainer 102.

Optionally, when necessary the cap 104 may be completely removed fromthe nipple 126 to enable the container 102 to be refilled with thevolatile liquid L through the nipple 126.

Referring to FIGS. 6A and 6B, a wick 120 is provided for absorbing thevolatile liquid composition L. The wick 120 has a length, a first end146 and second end 148. The first end 146 and a first portion of thelength of the wick 120 is surrounded by and in contact with the volatileliquid composition L, and the second end 148 and the remaining portionof the wick extend into the nipple 126. Optionally, as shown in FIGS. 5,6A and 6B a wick holder 122 may be provided on the interior of thenipple 126 to maintain the second end 148 of the wick within the nipple126.
